Projectile Motion
Physics ⇒ Mechanics
Projectile Motion starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Projectile Motion.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A ball is projected horizontally from a 45 m high cliff with a speed of 10 m/s. How far from the base of the cliff will the ball land? (Take g = 10 m/s²)
A ball is thrown at 10 m/s at an angle of 60° above the horizontal. What is the time of flight? (Take g = 10 m/s², sin 60° = 0.87)
A ball is thrown at 15 m/s at an angle of 37° above the horizontal. What is the horizontal component of its velocity? (cos 37° = 0.8)
A ball is thrown at 20 m/s at an angle of 0° above the horizontal. What is its range if it lands at the same height? (Take g = 10 m/s²)
A ball is thrown horizontally from a height of 80 m with a speed of 5 m/s. How long will it take to hit the ground? (Take g = 10 m/s²)
A ball is thrown horizontally from the top of a 20 m high building. How long does it take to reach the ground? (Take g = 10 m/s²)
A projectile is launched at 10 m/s at 30°. What is its initial vertical velocity? (sin 30° = 0.5)
A projectile is launched at 20 m/s at 60° to the horizontal. What is the time taken to reach the maximum height? (Take g = 10 m/s², sin 60° = 0.87)
A projectile is launched at 25 m/s at 53° above the horizontal. What is its maximum height? (Take g = 10 m/s², sin 53° = 0.8)
A projectile is launched at 30 m/s at 45°. What is its range? (Take g = 10 m/s², sin 90° = 1)
A projectile is launched from the ground and lands at the same level. At what point is its speed minimum?
A stone is thrown at 20 m/s at an angle of 30° above the horizontal. What is the initial vertical component of its velocity? (sin 30° = 0.5)
A stone is thrown horizontally from a 20 m high tower with a speed of 8 m/s. How far from the base will it land? (Take g = 10 m/s²)
If a projectile is launched at an angle of 45° with the same initial speed as one launched at 30°, which will have a greater range?
If a projectile is launched at an angle θ, what is the relationship between the ranges for angles θ and (90° - θ) with the same initial speed?
If the acceleration due to gravity on the Moon is 1/6th that on Earth, how will the range of a projectile (with same initial velocity and angle) compare on the Moon to that on Earth?
